Hi Peter: Thank you, Your idea is very good, It's an type of unequal constraint joints. In fact, current code framework is open for more extensions of joints, I'll write documents of how to use and how to write further extensions or patches soon. of course, This joint can be implemented by any of us. The current project is just a rudiment (even coding and debugging are not all finished yet), I hope you can work with us to make it better, Thank you again. Best Wishes Zhang Fan
Peter Gebauer <[EMAIL PROTECTED]> 写道： Hello again. Is there a list of planned features for the finished module? Specifically, I'm thinking of joint restrictions on rotation, as an example joint.restriction = 10, 349 # joint can only rotate between 10 and 349 # degrees. joint.restriction = -10, 10 # joint can only rotate between 350 (-10) and 10 # degrees. It would also be really sweet if one could apply a target angle and applied force to reach that target angle, that way you could simulate things bending joint.target_angle = (90, 2.0) # whenever the joint is rotated away from 90 # degrees angle, apply 2.0 force in the # correct direction to work it's way towards # 90 degrees. joint.target_angle = (0, inf) # unbendable, joint stuck at 0 degrees. Maybe there's a better way to achieve this? Anyway, if something like this is implemented it will be very easy to make ragdolls, springs, etc. /Peter On 2008-06-19 (Thu) 12:17, 帆 张 wrote: > Hi , > > Thank you very much, I'd like to see your advices and get help from you.
